Corso di Storia della Probabilità a Pavia
by Antonio Lijoi 17 Mar '16

17 Mar '16

Nell'ambito delle attivita' del Dottorato di Ricerca in Matematica (Universita' di Pavia - Universita' di Milano Bicocca - INdAM), il prof. Eugenio Regazzini terra' il corso ** History of Probability in the First Half of XX Century ** Le lezioni (30 ore complessive) si terranno presso il Dipartimento di Matematica "F. Casorati" dell'Universita' di Pavia, ogni giovedi' e venerdi' dalle 10:00 alle 13:00, a partire dal 14 aprile. Per ulteriori informazioni e' possibile contattare il docente via email: eugenio.regazzini(a)unipv.it ** Descrizione del corso ** The first half of the last century has been a formidable period for the development of probability and its applications. In point of fact, during its course a number of open problems found a definitive answer and, at the same time, sound bases towards new important achievements were established. The method adopted in the present course in order to illustrate the advance of probability consists in analyzing the most original and streamlined lines of reasoning to prove a certain number of theorems generally seen as determining the magnificence of modern probability. Since the aforesaid progress has been made possible even by the axiomatization of probability, the first part of the course will be devoted to this subject, drawing particular attention to the foundational work of A. N. Kolmogorov (1933) and B. de Finetti (1931). The second part will deal with distinguished versions of the strong law of large number, starting from E. Borel (1909) and F.P. Cantelli (1917), to get at the general formulation from the Soviet School (Kolmogorov, A. Khinchin, etc.). In the case of stochastic independence, their extensions to exchangeable random elements (de Finetti), and more general stationary sequences (ergodic theorem of von Neumann and Birkhoff) will be displayed and discussed. In this very same part, the role played by stable and infinitely divisible laws to solve the central limit problem (P. Lévy, Khinchin, W. Doeblin, B. Gnedenko) will be emphasized. The last part will be devoted to the birth of the theory of stochastic processes, starting from the works of Kolmogorov (1929) on Markov processes, de Finetti (1929 -1933) and Lévy (1934-1935) on random functions with independent increments, Lévy (1935-1937) and J. Doob (1940) on martingales. This last part will end with an outline to the methods devised in the fifties to study convergence in law of stochastic processes.

Half day in stochastic processes and mathematical finance
by Tiziano Vargiolu 11 Mar '16

11 Mar '16

It is a pleasure to announce that on March, 14 in Room 2BC/30 of the Department of Mathematics at the University of Padova (via Trieste, 63) there will be two seminars and the discussion of a PhD thesis. The plan of the morning is as follows: 10am Prof. Carlo Sgarra (Politecnico di Milano): "American options valuation in stochastic volatility models with transaction costs" (joint with A. Cosso and D. Marazzina) 11am Prof Fausto Gozzi (LUISS Roma): "HJB equations for stochastic control problems with delay in the control: regularity and feedback controls" (joint with Federica Masiero) 12am Dr Matteo Basei will defense his PhD thesis titled "Topics in stochastic control and differential game theory, with application to mathematical finance" Here below the abstracts of the presentations. ABSTRACT SGARRA In the present paper we analyze the American option valuation problem in a stochastic volatility model when transaction costs are taken into account. We shall show that it can be formulated as a singular stochastic optimal control problem, proving the existence and uniqueness of the viscosity solution for the associated Hamilton-Jacobi-Bellman partial differential equation. Moreover, after performing a dimensionality reduction through a suitable choice of the Utility Function, we shall provide a numerical example illustrating how American options prices can be computed in the present modeling framework. ABSTRACT GOZZI Stochastic optimal control problems governed by delay equations with delay in the control are usually more difficult to study than the the ones when the delay appears only in the state. This is particularly true when we look at the associated Hamilton-Jacobi-Bellman (HJB) equation. Indeed, even in the simplified setting (introduced first by Vinter and Kwong [44] for the deterministic case) the HJB equation is an infinite dimensional second order semilinear Partial Differential Equation (PDE) that does not satisfy the so-called "structure condition" which substantially means that "the noise enters the system with the control". The absence of such condition, together with the lack of smoothing properties which is a common feature of problems with delay, prevents the use of the known techniques (based on Backward Stochastic Differential Equations (BSDEs) or on the smoothing properties of the linear part) to prove the existence of regular solutions of this HJB equation and so no results on this direction have been proved till now. In this paper we provide a result on existence of regular solutions of such kind of HJB equations and we use it to solve completely the corresponding control problem finding optimal feedback controls also in the more difficult case of pointwise delay. The main tool used is a partial smoothing property that we prove for the transition semigroup associated to the uncontrolled problem. Such results hold for a specific class of equations and data which arises naturally in many applied problems. ABSTRACT BASEI: We consider three problems in stochastic control and differential game theory, arising from practical situations in mathematical finance and energy markets. First, we address the problem of optimally exercising swing contracts in energy markets. Our main result consists in characterizing the value function as the unique viscosity solution of a Hamilton-Jacobi-Bellman equation. The case of contracts with penalties is straightforward. Conversely, the case of contracts with strict constraints gives rise to stochastic control problems where a non-standard integral constraint is present: we get the anticipated characterization by considering a suitable sequence of unconstrained problems. The approximation result is proved for a general class of problems with an integral constraint on the controls. Then, we consider a retailer who has to decide when and how to intervene and adjust the price of the energy he sells, in order to maximize his earnings. The intervention costs can be either fixed or depending on the market share. In the first case, we get a standard impulsive control problem and we characterize the value function and the optimal price policy. In the second case, classical theory cannot be applied, due to the singularities of the penalty function; we then outline an approximation argument and we finally consider stronger conditions on the controls to characterize the optimal policy. Finally, we focus on a general class of non-zero-sum stochastic differential games with impulse controls. After defining a rigorous framework for such problems, we prove a verification theorem: if a couple of functions is regular enough and satisfies a suitable system of quasi-variational inequalities, it coincides with the value functions of the problem and a characterization of the Nash equilibria is possible. We conclude by a detailed example: we investigate the existence of equilibria in the case where two countries, with different goals, can affect the exchange rate between the corresponding currencies.
